I'm trying to use a "Lenovo VDK8736 USB Port replicator with digital video" with Fedora/Gnome 20 64-bit. I'm finding that the USB display adapter is not detected despite the necessary driver (udl) being found and loaded and the corresponding /dev/fb? device being created.

How do I get the new video adapter to be detected with the Gnome desktop?

Supporting information below:

The USB display adapter uses DL165 chipset.

lsusb reports: Bus 003 Device 003: ID 17e9:01e6 DisplayLink

lsmod shows udl driver loaded:

#lsmod | grep udl

udl 24618 1

drm_usb 12990 1 udl

drm_kms_helper 50287 2 udl,i915

drm 283349 8 udl,i915,drm_usb,drm_kms_helper

The udl driver is provided by base kernel package as shown by:

#rpm -qf /usr/lib/modules/3.12.5-302.fc20.x86_64/kernel/drivers/gpu/drm/udl/udl.ko

kernel-3.12.5-302.fc20.x86_64

Two frame buffer devices present:

#ls -ld /dev/fb*

crw-rw----. 1 root video 29, 0 Jan 13 11:09 /dev/fb0

crw-rw----. 1 root video 29, 2 Jan 13 13:49 /dev/fb2

fb2 corresponds to the udl driver.

Make sure you use X.org, though. I only can get DisplayLink to work on X.org, never Wayland.

Additionally, I installed the driver from the manufacturer using this script to generate the RPM packages https://github.com/displaylink-rpm/di... (but looks like you have the driver loaded already, but try it just in case dont forget to rebot after installing)
